Someone on the #solr IRC channel asked about where they can get ZK version 3.4.6, since that's what's included in the most recent version of Solr (5.4.0 is a day or two from release).
When I first looked, and couldn't even find it on the "archives" link that's present on each mirror, I initially suggested that the user should use 3.4.7 instead. I'd like to know whether there is enough binary compatibility with 3.4.6 for this to be a reasonable suggestion. Since it's a point release and not a new minor version, this seems likely. Further digging shows that releases up to 3.3.2 are in the hadoop/zookeeper archive location, with newer archived releases in the zookeeper archive location. I'm guessing that 3.3.3 was the first release after the project was promoted to top level. Thoughts about making this situation better: Change the "archives" link on the mirror page to the zookeeper archive location (newer versions). Both archive locations should have links pointing at the other archive location. Thanks, Shawn
